The Effects of Maxillomandibular Advancement and Genioglossus Advancement on Sleep Quality

Maxillomandibular advancement (MMA) using a standardized surgical procedure consisting of a LeFort I osteotomy and bilateral sagittal split ramus osteotomy and genioglossus advancement (GA) using a genioplasty improve airway volume, oxygen desaturation, and the AHI in patients with OSA. However, there are few reports on changes in sleep quality following MMA and GA. We assessed the effects of MMA and GA on sleep quality by comparing oxygen desaturation, AHI, and sleep architecture before and after surgery. Methods: Eight patients underwent polysomnography (PSG) and CT scan before and after surgery. Conclusions: Our study finds that %TST and %REM were both increased, while %S1 and NA both decreased. Based on these results, it appears that both the quality and quantity of sleep were improved. MMA and GA improve sleep respiratory disturbance and can also improve sleep quality

Trigeminal Schwannoma Presenting with Masticatory Muscle Atrophy: A Rare Case Report

Trigeminal schwannoma (TS) presenting with masticatory muscle atrophy is very rare. Here, we report the case of an 80 year-old male patient with TS presenting with masticatory muscle atrophy in October 2014. The patient had been diagnosed with hypertrophic pachymeningitis and right intracranial TS in 2013 by his neurologist, for which he was treated with steroids. However, his symptoms in the trigeminal innervation region persisted. He visited our department due to difficulty in opening his mouth as well as eating. Surgery was not performed owing to his advanced age and general condition. His trismus was improved by mouth opening training via manual manipulation for three years. We suggest that TS should be considered in the differential diagnosis of patients with masticatory muscle atrophy. Consultation with a neurologist is also essential. Manual manipulation may be an effective non-surgical treatment option for patients with difficulty in mouth opening owing to TS
